I am using @googlemaps/js-api-loader in my Nuxt 3 website. Everything works fine in local development, but when I try to build the project with nuxt generate (no matter if locally or on Vercel) I'm getting following error:

[nuxt] [request error] Named export 'Loader' not found. The requested module 'file:///path/to/website/node_modules/@googlemaps/js-api-loader/dist/index.umd.js' is a CommonJS module, which may not support all module.exports as named exports. CommonJS modules can always be imported via the default export, for example using:

The important part of loading script looks like this:

import { Loader } from '@googlemaps/js-api-loader';

const loader = new Loader({
    apiKey: config.googleMapsApiKey,
    version: 'weekly',
});

onMounted(async() => {
    await loader
        .load()

        ...

so I tried to import this package differently, e.g.:

import * as gmaps from '@googlemaps/js-api-loader';
const { Loader } = gmaps;

and the previous error disappeared, but now I'm getting

[Vue warn]: Unhandled error during execution of setup function
  at <DynamicLocations class="contact__map" locations= [
  {
    id: 1,

...

I also can't import package by default export. Do you have any ideas what's going on and how can I fix this?

• javascript
• vue.js
• google-maps
• nuxt.js
• vercel

• 1 Importing the entire library worked for me, which of course is not ideal. I opened an issue on GH. github./googlemaps/js-api-loader/issues/692 – braitsch Commented Sep 27, 2022 at 18:39

I found a documentation page related to this problem and there is the following information:

If you encounter these errors, the issue is almost certainly with the upstream library. They need to fix their library to support being imported by Node.

Although they provide a solution to get rid of errors by adding the package to build.transpile:

 build: {
     transpile: ['@googlemaps/js-api-loader'],
 },

It worked for me
